SDK Expands SIC wafer Capacity

News
Starts mass production of high grade wafers with basal plane dislocations within 0.1/cm2


Showa Denko (SDK) has expanded its capacity for making high-quality-grade SiC epitaxial wafers for power device  marketed under the trade name of High-Grade Epi (HGE) and also started mass production. 

The expanded production facility has the capacity to produce 3,000 wafers per month, based on a conversion into SiC epitaxial wafers for power devices having withstanding voltage of 1,200V.

HGE is a grade of SiC epitaxial wafer with very low crystal defect density, developed and commercialised by SDK in October 2015. Since the launch of HGE, SDK has been working on sample shipments of it to device manufacturers. HGE contributes to an improvement in reliability of SiC-MOSFET by controlling the number of basal plane dislocation within 0.1/cm2.

Moreover, the establishment of technology to lower the number of defects has enabled the company to mass-produce thick-film (100µm or more thick) epitaxial wafers and p-type epitaxial wafers, both for potential use in bipolar power devices.

These special epitaxial wafers are difficult to produce with conventional technologies. SDK expects that thick-film HGE market will significantly contribute to the development of SiC-IGBT, which can be used as ultra-high-voltage devices for power generation/transmission systems.

The size of the market for SiC epitaxial wafers for power devices is expected to reach 100 billion yen in 2025 as the early use of SiC power devices in vehicles is under consideration. SDK will continue meeting the need of the market for high-quality SiC epitaxial wafers, aiming to contribute to the improvement in energy efficiency of power devices.
